Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494726, here are decompositions:

5 + 31494721 = 31494726
13 + 31494713 = 31494726
19 + 31494707 = 31494726
37 + 31494689 = 31494726
47 + 31494679 = 31494726
83 + 31494643 = 31494726
89 + 31494637 = 31494726
173 + 31494553 = 31494726

Showing the first eight; more decompositions exist.
